Two very remarkable, though seemingly unrelated, changes have taken place in the U.S. economy in the past two years. The first is well known—the remarkable growth of the Internet. The second is not well-known—that in 1997 and 1998, while the U.S. economy grew by some 8%, U.S. energy consumption hardly grew at all, about 1%. Had the historical relationship between U.S. economic growth and energy consumption been the same in those two years as it had in the previous 10, we might have expected 6% growth in energy consumption. This is potentially very important because the vast majority of air pollution in this country come from the production and use of energy. In particular, virtually all of the emissions of carbon dioxide, the principal greenhouse gas emitted by human activity, come from fossil fuel combustion. Indeed, U.S. emissions of greenhouse gases rose only 0.2% in 1998, the smallest rise since 1991, a recession year.3
If the relationship between energy use and economic growth is changing, that would have profound implications for long-term economic and energy forecasting in this country. It would affect key national issues such as how costly it will be for the United States to reduce its emissions of heat-trapping gases that scientists believe contribute to global warming and climate change. Since the science of global warming has been the subject of thousands of studies, we will not discuss it here.4
There are, as we will see, a variety of reasons why U.S. energy intensity may be changing. The question of primary interest in this paper, however, is whether there is any connection between the growth of the Internet and energy trends. Energy use in the United States divides roughly evenly between buildings, manufacturing, and transportation. The Internet has the ability to turn retail buildings into Web sites and to turn warehouses into better supply chain software, to dematerialize paper and CDs into electrons, and to turn trucks into fiber optic cables. After the Introduction, and a section on recent trends affecting energy consumption, the paper will focus on how the Internet may affect energy usage in those three sectors of the economy.
We recognize that the quality of the numbers and metrics available on the current and future state of the Internet economy leave much to be desired. Indeed, much of the data and forecasting come from firms engaged in e-commerce, market research, or management consulting, who all have an incentive “to build momentum” for the activity they are analyzing.5 Even the terms electronic commerce and Internet economy, which are achieving widespread usage, do not have agreed-upon definitions.6
Very few energy or environmental analyses of the impact of the Internet have been done.7 Environmental life-cycle analyses are very hard to do well and engender much skepticism.8 The recent literature attempting to determine the net energy and environmental benefits of telecommuting is particularly sobering (see Section 5). Predicting the future is notoriously difficult in the technology arena. As Federal Reserve Board Chairman Alan Greenspan, one of the IT optimists, told Congress in June: “Despite the remarkable progress witnessed to date, we have to be quite modest about our ability to project the future of technology and its implications for productivity growth and for the broader economy.”9 This is doubly true in the energy arena, where flawed predictions are the norm. That is why it we have labeled this paper a scenario, borrowing the approach used by the most widely respected strategic planner in the energy business, Royal Dutch/Shell. Indeed, a major reason we are writing this White Paper is to raise issues that we believe deserve far more rigorous analysis than we have been able to perform, particularly by those who have made energy predictions without considering the impact of the Internet.
While the precise future impact of the Internet cannot be known today, one thing is already clear—the Internet is poised to have a powerful effect. As Federal Reserve Board Chairman Alan Greenspan told Congress in June:
Something special has happened to the American economy in recent years.
An economy that twenty years ago seemed to have seen its better days is displaying a remarkable run of economic growth that appears to have its roots in ongoing advances in technology….
[I]nnovations in information technology—so-called IT—have begun to alter the manner in which we do business and create value, often in ways that were not readily foreseeable even five years ago.10
THE EXPLODING INTERNET ECONOMY
The number of Internet users in the United States alone has soared from 5 million in 1993 to 62 million in 1997 to over 100 million as of mid-1999. According to the Department of Commerce’s first major report on e-commerce, published in April 1998, “The Internet’s pace of adoption eclipses all other technologies that preceded it. Radio was in existence 38 years before 50 million people tuned in; TV took 13 years to reach that benchmark. Once it was opened to the general public, the Internet crossed that line in four years.”11 Internet traffic doubles every 100 days.12 Over 2 billion orders will be placed over the Internet in 1999.13 Already, the Web is used by people representing some 60% of the total purchasing power of U.S. households.
The rapid growth of the Internet makes it difficult to understand its current impact, let alone its future impact. In part this is due to Metcalfe’s Law of Networks, which states that the usefulness of the network equals the square of the number of users. In other words, while the number of users grows arithmetically, the value and impact of the Internet grows exponentially. The authors of the 1998 book, Unleashing the Killer App, explain that “the more people who use your software, your network, your standard, your game, or your book, the more valuable it becomes and the more new users it will attract, increasing both its utility and the speed of its adoption by still more users.”14 They note that having one phone is useless, a few phones are of limited value, and one million phones create a vast network. Indeed, the Internet makes possible an even more powerful network than telephones, as noted in a report by the University of California’s E-conomy Project: “Unlike prior communication systems, such as telephony, which established a dedicated connection between two (or sometimes more) nodes, the Internet allows the simultaneous exchange of information in digital form among an unlimited number of nodes…. To this is added the innovation of hypertext, that is, the ability to almost effortlessly move from node to node at a whim.”15
Online auctioning is a particularly potent example of the Internet’s network effect. The Internet is beginning to create almost a virtual nationwide barter economy for a wide variety of goods and services. Not just Beanie Babies and Pez Dispensers are being auctioned but, as we will see, basic commodities like steel and paper, and even empty space on cargo trucks, which alone could potentially save a great deal of energy.
Many if not most Americans have become familiar with the brand-name business-to-consumer e-commerce sites, such as Amazon.com, Ebay, Blue Mountain, and Travelocity. The far bigger economic impact lies elsewhere, as explained in the September 1999 issue of Business 2.0 by Mohanbir Sawhney, who heads the e-commerce and technology group at the Kellogg Graduate School of Management at Northwestern University, and Steven Kaplan, faculty director of the entrepreneurship program at the University of Chicago Graduate School of Business:
The great untold story of online commerce is that business-to-business sales have already eclipsed the higher-profile business-to-consumer market by a long shot. Annual B-to-B e-commerce is projected to soar from $43 billion in 1998 to $1 trillion by 2003, according to Forrester Research, while the consumer market swells from $7.8 billion to $108 billion in the same period.16
We will see in later sections the power of Metcalfe’s Law as it applies to businesses like IBM, Cisco Systems, and GE—the exponential impact achieved as more and more companies put their supply chain on the Internet. GE, for instances, estimates that streamlining purchases via the Internet could save the company between $500 and $700 million annually.17 CEO Jack Welch told Business Week in June, “I don't think there's been anything more important or more widespread in all my years at GE. Where does the Internet rank in priority? It's number one, two, three, and four.”18
The Internet has an astonishing ability to eliminate inefficiency and increase capacity utilization across the entire economy. It may be helping to create a so-called “New Economy” with much higher rates of productivity growth than in the past two decades.
While the Internet economy remains a small share of the total U.S. economy, it represents a much higher fraction of the growth in the economy. In July 1999, the Department of Commerce’s second major study on The Emerging Digital Economy presented a detailed analysis of the industries that produce Information Technology (IT), such as computers, semiconductors, telephone equipment, software, programming, computer services.19 The Commerce Department said those IT-producing industries had reached nearly an 8% share of the U.S. economy by the end of 1998, but that they were responsible for 28% to 29% of the contribution to real growth during 1997 and 1998.
Further, those numbers do not include everything that is typically included in a definition of the Internet Economy: all of the additional sales over the Internet during those two years by traditional industries that were taking advantage of the output of these IT-producing industries and creating Web sites, intranets (internal networks) and extranets (networks extended to a limited number of participants outside the company, such as suppliers). One preliminary effort to capture the combined impact of all facets of the Internet Economy has been done by the Center for Research in Electronic Commerce of the Graduate School of Business at the University of Texas at Austin. They concluded in October:
“U.S. GDP is projected to grow $340 billion in 1999. The projected $200 billion growth in Internet Economy in 1999 plays a significant role in the health of the economy, although differences between GDP and revenues make a precise comparison difficult.”20
So, the Internet Economy is playing an increasingly dominant role in the nation’s overall growth. It is the issue of incremental growth that is most relevant for this paper, since we are exploring whether information technology and the Internet allow a different kind of economic growth, one that does not require as much growth in energy consumption as traditional economic growth.
A WEIGHTLESS AND FRICTIONLESS WORLD?
“Computers in the future may … perhaps weigh only 1½ tons.”21
Popular Mechanics, 1949
Dematerialization is a long-standing and well-studied trend in the economy.22 The idea that information technology (IT) and electronic commerce in particular can reduce our material and energy consumption is also not a new one. In an October 1996 speech, Federal Reserve Board Chairman Alan Greenspan said,
Virtually unimaginable a half century ago was the extent to which concepts and ideas would substitute for physical resources and human brawn in the production of goods and services. In 1948 radios were still being powered by vacuum tubes. Today, transistors deliver far higher quality with a mere fraction of the bulk. Fiber-optics has replaced huge tonnages of copper wire, and advances in architectural and engineering design have made possible the construction of buildings with much greater floor space but significantly less physical material than the buildings erected just after World War II. Accordingly, while the weight of current economic output is probably only modestly higher than it was a half century ago, value added, adjusted for price change, has risen well over threefold.
The displacement of human physical effort by ideas is, of course, also evident in changed production processes. Word processors have markedly reduced the effort required to produce a manuscript. Turn-of-the-century steel mills, and even those operating in 1948, valued the physical brawn that could move coiled sheets from one segment of a plant to another. Today, we perform these tasks with devices whose mechanical leverage is designed and guided by the insights coded into a computer program.
Radical transformations in what we produce in the way of goods and services and how we produce them occur perhaps once or twice in a century, at most.23
Inspired in part by Greenspan, Diane Coyle, economics editor of The Independent, wrote a book titled, The Weightless World: Strategies for Managing the Digital Economy.24 The digital world, she notes, is about as close to weightless as is possible, allowing "nearly costless reproduction.” Danny Quah, a professor at the London School of Economics uses the term, “infinite expansibility,” meaning that the use of a dematerialized object by one person does not stop another person from using it also.25
In 1994, Wired magazine explained, “While those who produce electronic goods must expend the same capital, labor, and knowledge as those producing tangible goods, their products can be copied in nanoseconds and transported at the speed of light.”26 Similarly, Nicholas Negroponte, founder of MIT's Media Lab, wrote in his 1995 book, Being Digital, “The information superhighway is about the global movement of weightless bits at the speed of light.”27
Some have even calculated the increasing weight loss of the U.S. economy. Chris Meyer, director of the Ernst & Young Center for Business Innovation, reported in April 1999 the results of an analysis by the Center. “The value-to-weight ratio of a pound of GDP has gone from $3.64 in 1977 to $6.52 today, a 79 percent increase.”28 While U.S. GDP rose 70% in those two decades, the total weight of that gross domestic product actually declined slightly.
In a similar vein, McKinsey consultant Lowell Bryan has calculated that today U.S. companies “require 20% less in the way of tangible assets to produce a dollar's worth of sales than they did a generation ago.”29 The Internet, as we will see repeatedly throughout this paper, is likely to accelerate these trends.
A concept related to weightlessness is the way in which the Internet can dramatically reduce transaction costs.30 “The conventional wisdom regarding Internet competition,” according to an August 1999 paper on “Frictionless Commerce,” from the E-commerce division of MIT's Sloan School of Management, “is that the unique characteristics of the Internet will bring about a nearly perfect market … where retailer 'location” is irrelevant, consumers are fully informed of prices and product offerings, and retailers all make zero economic profit.”31
For consumers, getting good information on products and price is a key transaction cost. In the past, this might have involved such energy intensive activities as going to a library or a book store, visiting several different furniture stores or auto dealers, looking at several catalogs, and the like. Consumers in theory also benefit from the lower overhead of online merchants who don’t have to build and operate expensive retail space.
The MIT study concluded, “We find the prices on the Internet are 9-16 % lower than prices in conventional outlets, depending on whether taxes, shipping and shopping costs are included in the price.” They conclude, “There is lower friction in many dimensions of Internet competition.”32
For businesses, frictionless commerce and nearly cost-free transactions may be even more valuable, as major companies increasingly are using the Internet to get the lowest prices for their supplies. For instance, General Electric has developed a Web-based Trading Process Network linked to its suppliers; it features "electronic catalogs, the ability to make electronic purchases and the option of paying online with an electronic credit card.” The system has cut procurement cycle time in half, processing cost by one third, and the cost of goods purchased by 5% to 50%. As of mid-99, GE was doing over $1 billion worth of Web-based business annually.33
We think that the terms frictionless and weightless are apt analogies here. Friction causes energy to be lost. Frictionless commerce saves energy. Similarly, the more weight an object has, the more energy it typically takes to manufacture and transport.
ROYAL DUTCH/SHELL SCENARIO
Consider a “world in which new technologies, systems and lifestyles would deliver continuing improvements in energy efficiency so that average per capita consumption rises by only some 15% by 2060” even as the world sustained annual GDP growth of 3% (and population roughly doubles).34 A techno-fantasy? No, that's one of two planning scenarios developed in the mid-1990s by Royal Dutch/Shell Group, the world’s largest, publicly-traded oil company, widely viewed as a benchmark for strategic planning.35
Shell labels this scenario “Dematerialization.” It is “driven by convergent and mutually enhancing developments in information technology, telecommunications, materials and biotechnology which in turn could have considerable potential to change social values and with them lifestyles. If this indeed happened, we would experience a transition phenomenon as profound as that brought about by the invention of the automobile and subsequent developments in individual mobility during this century.”
In the dematerialization scenario, energy intensity (energy consumed per dollar of GDP) decreases 1.7% per year until 2030, and then 2% per year after that, a rate, Shell notes, “admittedly has only been seen for limited periods in the past.” As difficult as this possibility may be to achieve, it is worth noting, as the Economist magazine has written, “The only oil company to anticipate both 1973's oil-price boom and 1986's bust was Royal Dutch/Shell.”36
So large drops in energy intensity in the coming years, driven in part by IT and the Internet Economy, are certainly imaginable.
OUR SCENARIO
For the purposes of this paper, the scenario we are assuming is that, in the words of Chairman Greenspan, “something special has happened to the American economy” and the something special is IT and the Internet Economy. If there is a “New Economy,” as so many have speculated, then we believe there is a New Energy Economy, and we will explore it here. A goal of the paper is to see whether plausible estimates for the impacts of the Internet would be sufficient to have a noticeable impact on U.S. energy intensity.
The key issues that need to be understood in more detail are
-
How many standard economic activities can be made weightless and/or frictionless?
-
Of those that can, what fraction will?
-
How will business and consumer behavior change when they do?
-
How will those changes affect energy consumption?
We can think of a great many that might to greater or lesser extents: commuting; shopping; information gathering for items ranging from homes to cars; banking and bill paying; education; conferencing; photography; inventories; construction of new retail stores and commercial office buildings; printing encyclopedias, catalogs, newspapers, phone books, and ultimately books; manufacturing software and CDs.
E-commerce experts have uncovered a great many unexpected opportunities for generating “Internet efficiency,” which have begun saving some energy today and have the opportunity to save vast quantities of energy in the future. The Internet holds the potential to eliminate waste from needless overproduction or mistaken orders. Consider under-utilization: online auctions, popularized for the public through eBay, allow companies to hold auctions for excess capacity, including airline seats, empty space on trucks, manufacturing capacity, and such energy intensive goods as steel and paper.
After a discussion of recent trends affecting energy consumption, this paper will examine these issues and opportunities and discuss their possible impact on present and future energy consumption trends.
